HUGH J. BARRON, OF NEWV YORK, N. Y.

APPARATUS FOR REG ENERATING EXHAUST-STEAM.

SPECIFICATION forming part of Letters Patent No. 619,120, dated February 7, 1899.

Application filed December 10,1898. Serial No. 698,805. (No model.)

Improvements in Apparatus for Regenerating Exhaust-Steam, of which the following is a full, clear, and exact specification.

My invention relates to improvements in steam-engines, and has for its object more particularly to provide an apparatus whereby to economically regenerate the exhauststeam'discharged from the engine partly by contact or association with high-pressu re live steam maintained intermediate the boiler and engine and partly by compressing and superheating said exhaust and the unregenerated steam.

The object above set forth I am enabled to attain by means of my invention, which con sists in the novel details of construction and in the combination, connection, and arrangement of parts, as hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, wherein like letters of reference indicate like parts, Figure 1 is a front View of an apparatus constructed according to and embodying myinvention; and Fig. 2 is a section taken on the line 2 2 of Fig. 1, showing the apparatus proper in plan.

In said drawings, A designates the apparatus, comprising two separate cylinders B B, suitably mounted longitudinally upon a base B C and E denote pipes connecting said cylinders B B, which are secured to said cylin ders upon their upper surfaces, adjacent to their ends, and D and F denote similar pipes (not seen) connecting said cylinders and secured upon the under surfaces of said cylinders adjacent to their ends.

0 D E F denote valves arranged in the pipes OD E F, adjacent to their ends, secured to the cylinder B, and C D E F denote similar valves arranged in said pipes C D E F, adjacent to the ends, secured to the cylinder B, and aa denote levers which are secured to the projecting ends of the stems of said valves To one side of the apparatus is situated an exhauster and compressor, which may be of the ordinary piston form or any other construction which will serve to effectually remove the unregenerated steam or vapor from said apparatus A. However, I prefer to employ the apparatus herein shown and described, which comprises a casing G, having two'separate compartments G G therein provided with inlet and outlet ports and suitably supported upon a base G. Within the upper compartment G is supported in bearings a shaft H, both ends of which project beyond the walls of the compartment, and upon the portion of said shaft I-I within the said compartment GHsfixedafan-wheel 11. Upon the rear end of said shaft are fixed four eccentrics I, which are encircled by straps b and connected to the levers a of the valves 0 D E F of the cylinder B by links I, and adjacent to the casing is fixed a fly-wheel J, and upon the forward end of said shaft H are fixed four eccentrics K, encircled by straps d and connected to the levers a of the valves 0 D E F of the cylinder B by links K, and adjacent to the casing is fixed a gear-wheel L.

Within the lower compartment G is supported a shorter shaft L, having fixed thereon within the casing the fan-wheel M and upon its forward-projecting portion adjacent to the casin g a gear-Wheel M in gear With the gear-wheel L of the shaft H.

To the side of the exhauster and compressor is mounted upon a base N a cylinder N, hav-- ing arranged therein a coil of pipe N the ends N of which extend through the wall of said cylinder and are connected to a suitable heating apparatus-such, for example, as a Water-heater arranged in the boiler-furnace.

0 denotes the main live-steam pipe leading from the boiler to the engine, and 0 denotes a reducing-valve arranged in said main livesteam pipe. From the section of the main live-steam pipe 0 intermediate the boiler and reducing-valve O extends an inlet-pipe 0 which is connected intermediate the valves 0 C to the pipe 0, connecting the cylinders B B, and P denotes alive-steam-outlet pipe, one end of which is connected intermediate the valves E E to the pipe E and its other end connected to the inlet-port of the upper compartment G of the exhauster and compressor, and a further section P of said pipe is connected to the outlet-port of said com- I Q denotes the exhaust-steam-inlet pipe leading from the engine and connected interme- I diate the valves D D to the pipe D, connecting the cylinders B B, and Q denotes a diaphragm arranged in said pipe Q directly below the reducing-valve O in the main live-steam i ipe 0, said diaphragm having a stem e, pro- 1 gecting upward therefrom, terminating in a oke f, connected to the reducing-valve 0, whereby to automatically open or close the reducing-valve O as the pressure of the exhaust-steam within the pipe Q increases or diminishes, and R denotes the vapor or unrei generated-steam pipe, which is connected intermediate the valves F F to the pipe F and g to the inlet-port of the lower compartment G of the exhauster and compressor G.

port of said compartment G and the inle'tin the base of the cylinder N, and R denotes a pipe connecting the outlet in the top of said cylinder N with the section of the live-steam pipe 0 intermediate the reducing-valve O and the engine.

The operation of the apparatus is as fol-'- pounds, to be conducted from the boiler,

through the main steam-pipe O and after passing through the reducing-valve 0 be supplied to the engine at a uniform pressure of about one hundred pounds, the excess of live steam "(twenty-five pounds) or a portion thereof contained in the section of the pipe 0 intermediate the reducing-valve O and the boiler will be diverted and conducted into the cylinder B through the pipe '0 pipe 0, valve 0 and unite with the exhaust-steam contained in' said cylinder B, and thereby regenerate the same. This regenerated steam, of about one hundred and five pounds,will thence pass out of said cylinder B by way of the valve E, pipe E, and pipe P into the compartment G of the exhauster and compressor G, and strike the blades of the fan-wheel H therein, causing the same and the shaft H, to which they are secured, to rotate in the direction of the arrow, Fig. 1, and thence pass out of said compartment by way of the pipe P into the main steam-pipe O, and thence to the engine. Atthe same time the exhaust-steam from the engine will be returned directly to the cylinder B through the exhaust-steam pipe Q,

pipe D, and valve D and at about the same time, but before the reversal of the valve mechanism, the unregenerated steam which may remain in the cylinder B will be withdrawn or removed therefrom through the valve F, pipe F, and pipe R by the action of the fan-wheel M in the lower compartment G3 of the apparatus G, which is operated by the shaft L and gear-WheelM, fixed thereon in gear with the gear-wheel L on the shaft H in the upper compartment G and said unregenerated steam thence conducted through the pipe R and compressed into the cylinder N, superheated and expanded therein by the heat imparted thereto by the coil N arranged Within said cylinder, and the now regenerated steam conducted from said cylinder to the main steam-pipe 0 through the pipe R As soon as the operation above described has taken place the valve mechanism of both cylinders B and B will be reversed by the eccentrics I and K on the shaft H and cause thelive steam to enter the cylinder B through the pipes and C and'the valve 0 and after regenerating the exhaust-steam therein pass out of said cylinder B through the i valve E pipes E and P, through the upper R denotes a pipe connected to the outlet compartmentG of the apparatus G, and into the main steam pipe 0, the exhaust-steam now being returned directly to the cylinder B from the engine through the pipes Q and D and the valve D and the unregenerated steam remainingin the cylinder B withdrawn therefrom through the valve F and pipes F and R by the fan-wheel M in the lower compartment G of. the apparatus G, and thence conducted by the pipe R to the cylinder N, into whichsaid unregenerated steam will be compressed,superheated therein, and thence conducted to the main steam-pipe 0 through the pipe R Hereupon the valve mechanism of both cylinders will be again shifted by the operation of the eccentrics I and K on the shaft H of the apparatus G and the initial operation repeated, and so on.
